It all depends on the fuel you have available and will run on a daily basis. Tell us that and people can suggest a good suggestion. Until l then it's basically shots in the dark.

Aftermarket twins when you add in install kit, downpipes, inlets, dci, outlets, etc. cost the same as a single turbo. Unless you are buying REALLY inexpensive twins.

You can buy a single turbo speedtech kit for $3,600 all in. ACF/DR JB precision 6266/6466 etc. for 4k. A single turbo is inherently more reliable, power comes on and is more predictable, sounds better etc. That being said if you want twins get the RB GFs or Pure. Everything else seems to be literal garbage.

Pure. Where in Ca ? As people have mentioned, Ethanol will be your friend.
Theres a set of pure 600s being sold by someone on here in O.C.
2k with inlets and install kit. Brand new.

I'm still deciding between ST or upgraded twins, but just looking at STs, let me know your feedback on my pros & cons list:

Top Mount Pros
Looks better
Serviceability

Top Mount Cons
Harder install?
A lot of heat in the wrong places

Bottom Mount Pros
Better heat management
Quicker spool
Less O2 sensor wear?

Bottom Mount Cons
Serviceability

Top mount installs are about the same as bottom mount once you are in there. While I have never installed a bottom mount on this platform once you are in there it's not that much different assuming you get a top mount kit that fits well.

Heat in the wrong places? I have had zero heat issues in 2 years of ownership. Including 8+ hours in traffic, beating on it, etc. all in 1 day, zero issues. I moved my WW pipe which takes all of 5 minutes when you are in there. Other than that ceramic coated the manifold and DEI wrapped the downpipe with the supplied ACF turbo blanket. I did use a few DEI wire wraps on the wastegate SS lines but I am sure they are not needed, overkill. ZERO gold fucking reflective tape, stupidest shit I have ever seen. I did install the DR valvecover heat shield but I am sure I would be fine without it. Same with that I used a $20 t4 manifold inconel metal gasket. Not needed but whatever i wanted a bit of overkill.

I have yet to burn through an ADV 02 sensor, they come with a 1 year warranty.

As far as spool a log or correctly designed tubular will perform about the same up to a point, at some point the correctly designed tubular should perform better. The log should spool slightly better at lower HP as the runners are just so much shorter. A log will proobably be fine for 99% of the people on this platform. I'm amazed Speedtech doesn't make a log style top mount. I picked the best top mount manifold design which is the ACF kit. Compared to DR: shorter manifold runners and equal length, much better merges, tear drop waste gate ports, waste gates placed at the correct location right at the turbo, not a foot plus away, ACF has a 3.5 inch down pipe vs. 3'' DR downpipe, ACF never had any XI fitment issues, exact same price.

Once you pay for install kit, downpipes, inlets, dci, outlets, and quality aftermarket twins it's basically the same as a quality single turbo kit.

A single sounds 100x better and and is easier to control, more predicable, inherently more reliable, etc. A single turbo will also provide higher HP and TQ on pump gas than twins can. They blow too much hot air hence them needing E85 to make any decent numbers on pump gas.

We have over 50 people in the UK and EU running these turbos from Ispeedytech and they are very solid. All they need is a balance check (~150 euros)

https://www.ebay.co.uk/itm/Billet-Wh...d-d815bb929aad

Get these, balance em and be done with it. Turbos like these have become so common, there is nothing special about them anymore. Anyone can make them in good quality. Spending 2000+ on a set of stage2 turbos is just absurd. There is no need to spend extra money on turbos unless your going stage3 or higher.


@N54Bad This forum is not the best place to ask for advice. It is very one-sided, full of American product pushers and propaganda for "sponsoring" vendors. Not knowing they are bieng fed Chinese products. Most people with knowledge have already left the forum. Try s poolstreet forums or get yourself into some Whatsapp groups. There is actual knowledge there. We are starting to run these chinesiums into sub 7 second 100-200 times Let the parrots on these forums be.

Edit: The fact that you can't say s poolstreet here says enough. This forum has become a real cancer.

Hmm Join Date 03-06-2020, Number of posts 1.

Where did the bad forum mod touch you? Show us on the doll.

Also, SS blocks other forums the EXACT same way, you are being amazingly hypocritical. Type in BB.

Wow 50 people in the UK and EU so...less than 2 people per country. If you compare the US to the EU in land mass that would be less than 1 set of turbos per state. Not exactly what anyone would call a substantial install base.

Personally I hope the cheap chinesium turbos work out for people so they don't have to drop 2500+ on reliable twins. But posts like yours are not helping anyone's confidence in the products.

I think having your response available online will be helpful for others on the same path as me.

The sound is really what's pushing me to go single over twins. I would definitely want a 3.5" downpipe and I want to run that to a 3.5" exhaust instead of the dual 60mm pipes; better sound and big weight savings. Speedtech is only a 3" downpipe.

The reason I'm still thinking about twins is because I'm not after some big HP number so having quicker spool is something I value. If i do go single, it would be something on the smaller side, but I still have plenty of research to do there.

I have E85 available near me so I'm probably going to go stage 2 pump with the Motiv flex fuel kit for now until I blow these stockers.

Come over and we can go for a spin...when it is warmer and we can get traction that is.

I say beat the ever living shit out of the stockers and once they give up the ghost get the right kit, twins or single that works for you.

Damn Torgus, you have so much information.

I have a fully stock N54. I was hoping to spend 3K on a kit. Of course I'd do full maintenance on it beforehand. I really want to stick with 93 Pump Gas. Any recommendation?

If you're fully stock then you're gonna have to put aside some of that money for plugs, coils, intercooler, charge pipe and TMAP sensor. Then going single or twins will be about $4k on the cheap side, but then you will also need a tune.

Things add up quick. If your stock turbos are still pulling fine, then you should go the FBO route now and then burn those up first, then making the switch to upgraded twins will only be the cost of the new turbos.

Aha. Good recommendation. Thank you.
I didn't think about it like that. I've already ordered plugs and coils. Definitely will need all the bolt-ons.

As b92 said you will need to buy an IC and CP and TMAP at a minimum on top of usual maintenance, which can be expensive when 12 injectors cost 1400 from FCP uninstalled.

Good news is you can go FBO using used parts as there are plenty of partouts in the for sale selection. Not that going FBO is expensive, but you can do it super cheap now using used parts. On stock turbos inlets and outlets are not worth the hassle of the install in my opinion. So skip those unless you decided to go with upgraded twins. I should have never wasted my time and money on them.

For 3k I would say twins assuming it includes the IC and CP. For $600 more you can have a bottom mount speedtech kit. $400 more than that and you can have a single turbo top mount that can make 800whp on an unopened block with the right supporting mods and a bit of luck.

If you are stuck on 93 like me twins are going to top out around 500whp give or take. You can add meth to make more power like I do. A single turbo will have more headroom as it blows cooler air that is not going to predetontate or knock as early as twins will. Thus they usually make more HP. Yes, you can run a VERY small turbo which would end up about the same as twins.

I would go FBO using used parts, do the works yours, keep saving up some cash and and when they fail make your decision then as to what upgrade fits you and your budget the best. There are + and - to both twins and singles. I prefer a single.

Where are you seeing $4k for a top mount? ACF and Doc Race are both >$5k

If you order the 6266 your can get it in JB or BB. The 6466 gen2 only comes in BB. JB is 1k less brand new:

https://www.full-race.com/store/prec...266-cea-turbo/ <---$1,124.99

https://www.full-race.com/store/prec...466-cea-turbo/ <---$2,149.99

DR is $4,495.00 for a JB 6266 online. I swear it was 4k with a JB turbo...same with ACF. Perhaps I am miss-remembering? I bet it was during one of their sales now that I think about it that I saw 4k, I bet if you called up both with cash in hand ready to buy they would cut you a deal, especially if you bundled some other products. I still would go with ACF as it is a superior designed kit vs. DR.

A JB turbo is just fine, should spool basically the same.

https://speedtech.com/pages/n54-pricing <--- starts at $3,600

[cgbimmer]

Hey unless you are rich.. after researching online or with people you know running them for reliability get what you think is the safest less expensive twins All turbos can fail especially if you get the cheapest set with no upgraded oil port..twins if looking around 500 np great spool not a big lag user choice..
I almost went with tokitas or whatever but teamed up on group buy 1200 for my older design DAW turbos. just know they may or may not be balanced . you may get a balance sheet that looks drawn like a kid did it ..lol if you worry have them balanced
But I have 18,000 miles no issues at all custom BQ tune.
Main point gets pricey either way cp intercooler bov xhp flash mhd custom tune install kit dp ...lpfp 2 or 3 stage 2 easier can make for 140.00 using old bucket
I would make if you are handy 2 relocated short inlets with aem filters less money that the kits out there and I went 2 1/4 aluminum pipe.
Not to mention if old injectors might need new index 12 ones coils plugs Tranny flush
